  • Operates reliably from -20 °C to +60 °C with 330 mm bend radius

Enfain OM3 ST-ST Duplex Cable

The Enfain OM3 ST-ST duplex multimode fibre optic cable is built for 10G gigabit links across switches, servers and data-centre equipment. It suits installers who need a ready-made 20m patch cord with ceramic ferrules and a 3.0mm PVC jacket.

OM3 10-gigabit core at 850nm

The single specification that decides fit is the OM3 10-gigabit core operating at 850nm. It delivers 10G performance with typical insertion loss of .2dB and maximum insertion loss of .3dB, while return loss exceeds 38dB. The duplex ST-ST connectors match legacy ST ports on older switches and patch panels.

Thermals noise and power draw

Passive fibre carries no electrical power, so the cable generates no heat and produces zero noise. The 3.0mm jacket withstands a 330mm bending radius and is rated for 1000 insertion cycles across an operating range of -20°C to +60°C.

Perguntas sobre este artigo

What does the OM3 10-gigabit core rating mean for actual link speed?

The OM3 core is rated for 10 GbE transmission at 850 nm, so the cable will carry a 10 GbE signal across its 20 metre length.

What does the duplex ST connector interface limit in practice?

Duplex ST connectors provide two fibres for transmit and receive, locking with a bayonet twist, and the OM3 core caps the link at 10 GbE over multimode distances.

What physical space and bend radius does the 3.0 mm jacket need?

The 3.0 mm PVC jacket requires a minimum bend radius of 330 mm and an operating temperature range of -20 °C to +60 °C for reliable installation.
